Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing, specifically a cell power detection device. Background Technology

[0002] After the grid lines of the solar cell are fabricated, various parameters need to be tested. One of these tests is power detection, which involves illuminating the solar cell with a light source to generate electricity through photoelectricity. At the same time, the detection end of the detection mechanism is controlled to contact the grid lines on the surface of the solar cell to perform power detection.

[0003] The problem with existing power detection methods is that when the solar cells are loaded to the power detection station, the solar cells are prone to large positional deviations. Simply adjusting the position of the probe is not enough to ensure that the probe can be aligned with and contact the grid lines on the solar cell, thus affecting the detection accuracy. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a solar cell power detection device, the detailed technical solution of which is as follows:

[0005] A battery cell power detection device includes a feeding conveyor line, a first position detection mechanism, a feeding and handling mechanism, a rotary table, a second position detection mechanism, a power detection mechanism, and a unloading and handling mechanism, wherein:

[0006] At least one support is provided on the rotary table. The rotary table is configured to drive the support to rotate. The rotation path of the support is sequentially provided with a loading station, a power detection station and a unloading station.

[0007] The first position detection mechanism includes a first positioning camera, which is located above or below the feeding conveyor line, and the discharge end of the feeding conveyor line is set to correspond to the feeding station.

[0008] The feeding conveyor is configured to convey battery cells. The first position detection mechanism is configured to acquire the first position information of the battery cells located on the feeding conveyor or the first position information of the battery cells picked up by the feeding and handling mechanism. The feeding and handling mechanism is configured to pick up the battery cells from the feeding conveyor and adjust the position of the battery cells according to the first position information, and to transport the battery cells to the support located at the feeding station.

[0009] The second position detection mechanism includes a second positioning camera, which is positioned above or below the support at the loading station. The second position detection mechanism is configured to acquire second position information of the battery cell at the support at the loading station.

[0010] The power detection mechanism is set at the power detection station. The power detection mechanism is configured to adjust the position of the detection end of the power detection mechanism according to the second position information in order to perform power detection on the battery cell located on the support at the power detection station.

[0011] The unloading and handling mechanism is configured to remove the battery cells that have completed power testing from the support located at the unloading station.

[0012] The solar cell power detection device provided in this application firstly uses a first position detection mechanism and a feeding and conveying mechanism to feed the solar cells to be tested and adjust their positions during the feeding process, ensuring that the solar cells are accurately fed to the target position on the support. Subsequently, through the cooperation of a second position detection mechanism and a power detection mechanism, the power detection mechanism performs power detection on the solar cells after adjusting the position of the detection end.

[0013] As can be seen, before adjusting the testing end of the testing mechanism, the position of the solar cells had already been adjusted by the feeding and handling mechanism. This ensures that the testing end of the testing mechanism can be aligned with and contact the grid lines on the solar cells, thereby guaranteeing testing accuracy.

[0014] In some embodiments, the loading and conveying mechanism includes a first UVW adjustment module, a linear drive module, and a first suction member, wherein: the linear drive module is connected to a movable part of the first UVW adjustment module, and the first suction member is connected to a movable part of the linear drive module; the linear drive module is configured to drive the first suction member to move between the discharge end of the loading conveyor line and the loading station, so that the first suction member picks up the battery cells from the loading conveyor line and places the picked-up battery cells onto a support member located at the loading station; the first UVW adjustment module is configured to adjust the position of the battery cells according to first position information after the first suction member picks up the battery cells.

[0015] A simple and flexible feeding and handling mechanism is provided. It drives the first adsorption component to move through a linear drive module to realize the feeding and handling of battery cells. The first UVW adjustment module adjusts the position of the first adsorption component and battery cells during the feeding and handling process.

[0016] In some embodiments, the power detection mechanism includes a mounting frame, a lifting drive unit, a first sliding support plate, a second sliding support plate, a second UVW adjustment module, a probe plate, and an upper pressure plate, wherein: the lifting drive unit is disposed on the mounting frame; the first and second sliding support plates are both slidably connected to the mounting frame and are both drive-connected to the lifting drive unit, with the second sliding support plate located above the first sliding support plate; the second UVW adjustment module is disposed on the first sliding support plate, and the probe plate is connected to the movable part of the second UVW adjustment module, with a plurality of rows of probes disposed on the upper surface of the probe plate; the upper pressure plate is disposed on the second sliding support plate, and the power detection station is located between the upper pressure plate and the probe plate; the second UVW adjustment module is configured to adjust the position of the probe plate according to second position information, so that the plurality of rows of probes on the probe plate are aligned with the grid lines on the lower surface of the battery cell located at the power detection station; the lifting drive unit is configured to drive the first and second sliding support plates to slide toward the battery cell located at the power detection station, so that the plurality of rows of probes press against the grid lines on the lower surface of the battery cell, and the upper pressure plate presses against the upper surface of the battery cell.

[0017] After the solar cell rotates to the power detection station located between the upper pressure plate and the probe plate, the second UVW adjustment module adjusts the position of the probe plate according to the second position information of the solar cell, so that the probe on the probe plate is aligned with the grid lines on the lower surface of the solar cell. Subsequently, the lifting drive unit drives the first sliding support plate and the second sliding support plate to slide towards the solar cell, so that the probe presses against the grid lines on the lower surface of the solar cell, and the upper pressure plate presses against the upper surface of the solar cell. In this way, the power of the solar cell can be detected.

[0018] In some embodiments, the cell power detection device further includes a detector and a light source disposed above an upper pressure plate, the upper pressure plate being a plate made of a light-transmitting material; the light source is used to irradiate the upper surface of the cell pressed against the upper pressure plate and the probe plate, so that the cell generates electricity after absorbing the light irradiated by the light source; the detector is electrically connected to the probe to obtain the electrical parameters of the cell.

[0019] By setting up a light source, sunlight can be simulated, allowing the solar cells to generate electricity after absorbing the light. In this way, probes and detectors can work together to detect the current and voltage of the solar cells, and calculate the cell's power based on this data.

[0020] In some embodiments, the mounting bracket is provided with a guide rail extending in a vertical direction, and the first sliding support plate and the second sliding support plate are slidably connected to the guide rail; the lifting drive unit includes a first lifting drive member and a second lifting drive member, wherein the first lifting drive member is drivenly connected to the first sliding support plate, and the second lifting drive member is drivenly connected to the second sliding support plate; the first lifting drive member and the second lifting drive member are configured to synchronously drive the first sliding support plate and the second sliding support plate to move closer to or further away from each other along the guide rail.

[0021] The first and second lifting drive components independently drive the first and second sliding support plates to rise and slide, respectively, thereby achieving independent lifting control of the upper pressure plate and probe plate. Ultimately, this ensures that both the upper pressure plate and probe plate can contact the battery cells to press them together from the top and bottom.

[0022] In some embodiments, the support includes a perforated tray and a second adsorption member, wherein: the tray is connected to a rotating platform; the second adsorption member is disposed on the tray and located in the perforated area of ​​the tray, and the second adsorption member is used to adsorb and support the battery cells.

[0023] By setting the support as a hollowed-out tray and setting a second adsorption component in the hollowed-out area of ​​the tray, the tray can adsorb and support the battery cell, and ensure that the probe plate can press against the grid line on the lower surface of the battery cell.

[0024] In some embodiments, a buffer station located between the unloading station and the loading station is provided on the rotation path of the support member; four support members are provided on the rotary table, and the rotary table drives the four support members to pass through the loading station, the power detection station, the unloading station and the buffer station in sequence.

[0025] The number of support components set on the rotating platform is equal to the number of workstations set on the rotation path of the support components. This ensures that after each step rotation of the rotating table, there is a support component at each workstation, thereby realizing the synchronous implementation of each operation process and improving the efficiency of power detection.

[0026] In some embodiments, the cell power detection device further includes a feeding conveyor line and a rotating mechanism. The feeding conveyor line transports the removed cells that have completed power detection to the feeding conveyor line. The rotating mechanism is configured to pick up the cells from the feeding conveyor line and return the cells to the feeding conveyor line after rotating and reorienting them.

[0027] By setting up a feeding and conveying mechanism and a rotating mechanism, the battery cells that have completed power testing are fed into the system, thus automatically transporting them to the subsequent processing station. The rotating mechanism allows for the rotation and orientation of the battery cells during the feeding and conveying process, ensuring that the orientation of the tested battery cells meets the processing requirements of the subsequent processing station.

[0028] In some embodiments, the support member includes an adjacent first support area and a second support area, the second UVW adjustment module includes two UVW sub-modules, the two UVW sub-modules are arranged side by side on the first sliding support plate, and the probe plate includes a first probe sub-plate and a second probe sub-plate, the first probe sub-plate and the second probe sub-plate are respectively arranged at the drive ends of the two UVW sub-modules.

[0029] With this configuration, the support can support two solar cells simultaneously, and the second UVW adjustment module can perform synchronous power detection on the two solar cells through two UVW sub-modules, thereby improving detection efficiency.

[0030] In some embodiments, the feeding conveyor line includes a first feeding conveyor line and a second feeding conveyor line arranged side by side, the first feeding conveyor line and the second feeding conveyor line being used to convey the first battery cell and the second battery cell, respectively.

[0031] By configuring the feeding conveyor line, it is possible to simultaneously feed and transport two battery cells.

[0032] In some embodiments, the loading and transporting mechanism includes a first loading and transporting mechanism disposed on a first side of the loading conveyor line and a second loading and transporting mechanism disposed on a second side of the loading conveyor line, wherein: the first loading and transporting mechanism is configured to pick up a first battery cell from the first loading conveyor line, and adjust the position of the first battery cell according to the first position information of the picked-up first battery cell provided by the first position detection mechanism and transport the first battery cell to a first carrying area; the second loading and transporting mechanism is configured to pick up a second battery cell from the second loading conveyor line, and adjust the position of the second battery cell according to the first position information of the picked-up second battery cell provided by the first position detection mechanism and transport the second battery cell to a second carrying area; the second position detection mechanism is configured to acquire the second position information of the first battery cell and the second position information of the second battery cell; two UVW module groups are configured to adjust the positions of the first probe plate and the second probe plate respectively according to the second position information of the first battery cell and the second position information of the second battery cell to contact the first battery cell and the second battery cell; the power detection mechanism is configured to simultaneously detect the power of the first battery cell and the second battery cell.

[0033] As can be seen, after the first and second loading and transporting mechanisms simultaneously pick up the first and second battery cells, and after adjusting their positions, they simultaneously load and transport the first and second battery cells onto the support. Subsequently, the two UVW sub-modules of the second UVW adjustment module simultaneously adjust the positions of the first and second probe sub-boards, which then simultaneously perform power detection on the first and second battery cells, thereby further improving detection efficiency.

[0048] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] As described in the background section, in existing power detection methods, when the solar cells are loaded to the power detection station, the solar cells are prone to large positional deviations. Simply adjusting the position of the probe is not enough to ensure that the probe can be aligned with and contact the grid lines on the solar cell, thus affecting the detection accuracy.

[0050] Therefore, this application provides a battery cell power detection device. For example... Figure 1 As shown, the battery cell power detection device in this embodiment includes a feeding conveyor line 1, a first position detection mechanism (not shown in the figure), a feeding and handling mechanism 2, a rotary table 3, a second position detection mechanism 4, a power detection mechanism 5, and a discharging and handling mechanism 6, wherein:

[0051] The rotary table 3 is provided with at least one support member 31. The rotary table 3 is configured to drive the support member 31 to rotate. The rotation path of the support member 31 is provided with a loading station, a power detection station and a unloading station in sequence.

[0052] The first position detection mechanism includes a first positioning camera, which is located above or below the feeding conveyor line 1, and the discharge end of the feeding conveyor line 1 is set corresponding to the feeding station.

[0053] The feeding conveyor line 1 is configured to convey battery cells 100. A first position detection mechanism is configured to acquire first position information of the battery cells 100 located on the feeding conveyor line or the first position information of the battery cells 100 picked up by the feeding and handling mechanism 2. The feeding and handling mechanism 2 is configured to pick up the battery cells 100 from the feeding conveyor line 1, adjust the position of the battery cells 100 according to the first position information, and transport the battery cells 100 to the support member 31 located at the feeding station. That is, when the feeding conveyor line 1 feeds the battery cells 100 to the discharge end, or after the feeding and handling mechanism 2 picks up the battery cells 100 from the discharge end of the feeding conveyor line 1, the first positioning camera of the first position detection mechanism performs a photographic positioning of the battery cells 100, thereby obtaining the first position information of the battery cells 100. After adjusting the position of the battery cells 100 according to the first position information, the feeding and handling mechanism 2 transports the battery cells 100 to the support member 31 located at the feeding station.

[0054] The second position detection mechanism 4 includes a second positioning camera, which is positioned above or below the support member 31 at the loading station. The second position detection mechanism 4 is configured to acquire the second position information of the battery cell 100 located on the support member 31 at the loading station. That is, when the battery cell 100 is loaded and transported onto the support member 31 at the loading station, the second positioning camera of the second position detection mechanism 4 performs image positioning of the battery cell 100 to obtain the second position information of the battery cell 100.

[0055] The power detection mechanism 5 is set at the power detection station. The power detection mechanism 5 is configured to adjust the position of the detection end of the power detection mechanism 5 according to the second position information of the battery cell 100, so as to perform power detection on the battery cell 100 located on the support member 31 at the power detection station.

[0056] The unloading and conveying mechanism 6 is configured to remove the battery cell 100 that has completed power testing from the support 31 located at the unloading station.

[0057] The battery cell power detection device of this application embodiment first uses a first position detection mechanism and a loading and conveying mechanism 2 to load and convey the battery cell 100 to be tested, and adjusts the position of the battery cell 100 during the loading and conveying process to ensure that the battery cell 100 is accurately loaded onto the target position on the support 31. Subsequently, with the cooperation of a second position detection mechanism 4 and a power detection mechanism 5, the power detection mechanism 5 performs power detection on the battery cell 100 after adjusting the position of the detection end.

[0058] As can be seen, in this embodiment of the battery cell power detection device, the position of the battery cell has been adjusted by the feeding and conveying mechanism 2 before the detection end of the detection mechanism 5 is adjusted. In this way, it can be ensured that the detection end of the detection mechanism 5 can be aligned with and contact the grid lines on the battery cell 100 after adjustment, thereby ensuring detection accuracy.

[0059] To enable the first and second positioning cameras to locate the battery cells by taking pictures, optionally, the first and second positioning cameras can not only capture images of the battery cells 100, but also have built-in image recognition modules. These modules contain pre-stored image analysis algorithms. When executed, the image analysis algorithms analyze the images containing the battery cells acquired by the first and second positioning cameras, thereby identifying the battery cells from the images and locating them. Alternatively, the first and second positioning cameras can also be connected to a PLC controller or a host computer, which also contains pre-stored image analysis algorithms.

[0060] like Figure 3 As shown, optionally, the loading and conveying mechanism 2 includes a first UVW adjustment module 21, a linear drive module 22, and a first suction member 23, wherein: the linear drive module 22 is connected to the movable part of the first UVW adjustment module 21, and the first suction member 23 is connected to the movable part of the linear drive module 22. The linear drive module 22 is configured to drive the first suction member 23 to move between the discharge end of the loading conveyor line 1 and the loading station, so that the first suction member 23 picks up the battery cell 100 from the loading conveyor line 1 and places the picked-up battery cell 100 onto the support member 31 located at the loading station. The first UVW adjustment module 21 is configured to adjust the position of the battery cell 100 according to the first position information after the first suction member 23 picks up the battery cell.

[0061] The linear drive module 22 can be any existing linear drive module capable of driving the first adsorption component 23 to move between the discharge end and the loading station of the loading conveyor line 1, such as a synchronous belt drive module or a lead screw drive module. The first UVW adjustment module 21 can be an existing UVW adjustment platform. The UVW adjustment platform is a general positioning and adjustment mechanism, which is a three-axis parallel motion mechanism. It realizes the linear movement of the first adsorption component 23 in the X-axis direction and the Y-axis direction and the rotational movement in the horizontal plane through the parallel movement of three linear movement axes (U-axis, V-axis, W-axis), thereby adjusting the position of the battery cell 100 adsorbed by the first adsorption component 23.

[0062] like Figure 4 As shown, optionally, the power detection mechanism 5 includes a mounting frame 51, a lifting drive unit 52, a first sliding support plate 53, a second sliding support plate 54, a second UVW adjustment module 55, a probe plate 56, and an upper pressure plate (not shown in the figure), wherein: the lifting drive unit 52 is mounted on the mounting frame 51. The first sliding support plate 53 and the second sliding support plate 54 are both slidably connected to the mounting frame 51 and are both drive-connected to the lifting drive unit 52, with the second sliding support plate 54 located above the first sliding support plate 53. The second UVW adjustment module 55 is mounted on the first sliding support plate 53, and the probe plate 56 is connected to the movable part of the second UVW adjustment module 55, with several rows of probes arranged on the upper surface of the probe plate 56. The upper pressure plate is mounted on the second sliding support plate 54, and the power detection station is located between the upper pressure plate and the probe plate 56.

[0063] After the solar cell rotates to the power detection station located between the upper pressure plate and the probe plate 56, the second UVW adjustment module 55 is configured to adjust the position of the probe plate 56 according to the second position information of the solar cell, so that the plurality of rows of probes on the probe plate 56 are aligned with the grid lines on the lower surface of the solar cell. Subsequently, the lifting drive unit 52 is configured to drive the first sliding support plate 53 and the second sliding support plate 54 to slide toward the solar cell located at the power detection station, so that the plurality of rows of probes on the probe plate 56 press against the grid lines on the lower surface of the solar cell, while the upper pressure plate presses against the upper surface of the solar cell to prevent the solar cell from being lifted by the probes and causing a loose connection.

[0064] Similarly, the second UVW adjustment module 55 can use an existing UVW adjustment platform.

[0065] Optionally, the solar cell power detection device in this embodiment further includes a detector and a light source disposed above the upper pressure plate. The upper pressure plate is a light-transmitting material, such as a glass plate. The light source is used to illuminate the upper surface of the solar cell pressed against the upper pressure plate and the probe plate, so that the solar cell absorbs the light and generates electricity. The detector is electrically connected to the probe to obtain the electrical parameters of the solar cell, including the current and voltage generated by the solar cell. The detector ultimately calculates the power output of the solar cell by analyzing the current and voltage.

[0066] Referring again to Figure 4, optionally, the mounting bracket 51 is provided with a guide rail extending vertically, and both the first sliding support plate 53 and the second sliding support plate 54 are slidably connected to the guide rail. The lifting drive unit 52 includes a first lifting drive component 521 and a second lifting drive component 522, wherein the first lifting drive component 521 is driveably connected to the first sliding support plate 53, and the second lifting drive component 522 is driveably connected to the second sliding support plate 54. The first lifting drive component 521 and the second lifting drive component 522 are configured to synchronously drive the first sliding support plate 53 and the second sliding support plate 54 to move closer or further apart along the guide rail. Optionally, both the first lifting drive component 521 and the second lifting drive component 522 include two servo motors, which are respectively mounted on the two outer sides of the mounting bracket 51.

[0067] The first lifting drive component 521 and the second lifting drive component 522 independently drive the first sliding support plate 53 and the second sliding support plate 54 to rise and slide, respectively, realizing independent lifting control of the upper pressure plate and the probe plate 56. Ultimately, this ensures that both the upper pressure plate and the probe plate 56 can contact the battery cell, thereby pressing the battery cell 100 together from the upper and lower sides. The first lifting drive component 521 and the second lifting drive component 522 can also be driven by, for example, cylinders, linear motors, or other drive components.

[0068] Optionally, the support 31 includes a perforated tray and a second adsorption member, wherein the tray is connected to the rotary table 3. The second adsorption member is disposed on the tray and located in the perforated area of ​​the tray, and is used to adsorb and support the solar cell. Since the solar cell is located in the perforated area of ​​the tray, its lower surface is exposed to the tray, ensuring that the probe plate 56 can contact and press against the grid lines on the lower surface of the solar cell from below.

[0069] The second suction device could be, for example, a suction cup mounted on a tray.

[0070] like Figure 1 As shown, optionally, a buffer station located between the unloading station and the loading station is also provided on the rotation path of the support member 31. The rotary table 3 is provided with four support members 31, and the rotary table 3 drives the four support members 31 to pass through the loading station, the power detection station, the unloading station and the buffer station in sequence.

[0071] By setting the number of support members 31 on the rotating platform 3 to be equal to the number of workstations along the rotation path of the support members 31, it can be ensured that after each step rotation of the rotating table 3, there is a support member 31 at each workstation, thereby realizing the synchronous implementation of each operation process and improving the efficiency of cell power detection. Optionally, a detection camera is set at the buffer workstation to detect whether there are any missed cells and / or damaged cells on the support members 31.

[0072] like Figure 1 As shown, optionally, the battery cell power detection device in this embodiment of the application further includes a feeding and conveying mechanism 7 and a rotating mechanism 8. The feeding and conveying mechanism 7 transports the battery cell 100 that has been removed and has undergone power detection to the feeding conveyor line 7. The rotating mechanism 8 is configured to pick up the battery cell 100 from the feeding conveyor line 7 and, after completing the rotation and reorientation of the battery cell 100, put the battery cell 100 back onto the feeding conveyor line 7.

[0073] By setting up the unloading and conveying mechanism 7 and the rotating mechanism 8, the unloading and conveying of the battery cells 100 that have completed power testing is realized, thereby automatically conveying the battery cells 100 that have completed power testing to the subsequent processing station. By setting up the rotating mechanism 8, the rotation and orientation of the battery cells 100 during the unloading and conveying process is realized, so that the orientation of the battery cells 100 that have completed power testing meets the processing requirements of the subsequent processing station.

[0074] like Figure 1 and Figures 4 to 5 As shown, optionally, the support member 31 includes an adjacent first support area and a second support area, the second UVW adjustment module 55 includes two UVW sub-modules, the two UVW sub-modules are arranged side by side on the first sliding support plate 53, and the probe plate 56 includes a first probe sub-plate and a second probe sub-plate, the first probe sub-plate and the second probe sub-plate are respectively arranged at the drive end of the two UVW sub-modules.

[0075] With this configuration, the support 31 can support two solar cells simultaneously, while the second UVW adjustment module 55 and the probe plate 56 simultaneously perform power detection on the two solar cells, thereby improving detection efficiency.

[0076] Optionally, the feeding conveyor line 1 includes a first feeding conveyor line 11 and a second feeding conveyor line 12 arranged side by side, the first feeding conveyor line 11 and the second feeding conveyor line 12 being used to convey the first battery cell and the second battery cell, respectively.

[0077] By configuring the feeding conveyor line 1 to include a first feeding conveyor line 11 and a second feeding conveyor line 12 arranged side by side, the feeding conveyor line 1 can synchronously feed and convey the two battery cells, ultimately enabling the two battery cells to be synchronously fed into the first and second bearing areas of the support member 31.

[0078] like Figure 1 As shown, optionally, the feeding and conveying mechanism 2 is configured as two sets, namely a first feeding and conveying mechanism disposed on the first side of the feeding conveyor line 1 and a second feeding and conveying mechanism disposed on the second side of the feeding conveyor line 1. Wherein:

[0079] The first feeding and handling mechanism is configured to pick up the first battery cell from the first feeding conveyor line 1, and adjust the position of the first battery cell according to the first position information of the picked-up first battery cell provided by the first position detection mechanism, and transport the first battery cell to the first bearing area of ​​the support member 31.

[0080] The second feeding and conveying mechanism is configured to pick up the second battery cell from the second feeding conveyor line 1, and adjust the position of the second battery cell according to the first position information of the picked-up second battery cell provided by the first position detection mechanism, and transport the second battery cell to the second bearing area of ​​the support member 31.

[0081] The second position detection mechanism 4 is configured to acquire the second position information of the first battery cell and the second battery cell. The two UVW sub-modules of the second UVW adjustment module 55 are configured to adjust the positions of the first probe sub-plate and the second probe sub-plate of the probe plate 56 according to the second position information of the first battery cell and the second battery cell, respectively, so as to contact the first battery cell and the second battery cell respectively, so as to simultaneously perform power detection on the first battery cell and the second battery cell.

[0082] As can be seen, after the first and second loading and transporting mechanisms simultaneously pick up the first and second battery cells, and after adjusting their positions, they simultaneously load and transport the first and second battery cells onto the support 31. Subsequently, the two UVW sub-modules of the second UVW adjustment module 55 simultaneously adjust the positions of the first and second probe sub-boards, which then simultaneously perform power detection on the first and second battery cells, thereby further improving detection efficiency.

[0083] Based on the same inventive concept, this application also provides a method for detecting the power of a battery cell, which includes the following steps:

[0084] S1. Obtain the first position information of the battery cell.

[0085] S2. Adjust the position of the battery cell according to the first position information of the battery cell and move the battery cell to the loading station.

[0086] S3. Obtain the second position information of the battery cells at the loading station.

[0087] S4. Transfer the battery cells located at the loading station to the power testing station.

[0088] S5. Adjust the position of the probe according to the second position information of the battery cell.

[0089] S6. Perform power detection on the battery cells.
